Welcome Bonus Options
When you sign up with the site, you can choose a Rainbet welcome bonus that matches your preferred play style. We think this is a better system than splitting the bonuses between “Casino” and “Sports”.
Wager Welcome Bonus — Up to $2,100 (40x WR)
The first option is a higher-value welcome package that comes with wagering requirements (40x). You get a deposit bonus for each of your first three deposits and receive a number of Free Spins on top.
Here’s how it works:
1st Deposit - 100% + 20 Free Spins
2nd Deposit - 50% + 20 Free Spins
3rd Deposit - 100% + 20 Free Spins
With the maximum deposit amount per deposit being $700, you can claim a total bonus of $2,100 across your first three deposit.
No-Wager Welcome Bonus - Up to $700
If you don’t want to be dealing with wagering after claiming your bonus, you can opt for the no-wager welcome bonus instead.
It’s a 100% bonus which you can redeem as you bet. The minimum deposit amount for this bonus is $30, while the maximum 100% bonus you can claim is $700.

Rainbet Promo Code vs Referral Code
The terminology used here is designed to help you find the code you're looking for, regardless of what you search for.
Technically, Rainbet refers to this as a “referral code”, however, it works in the same way as what is commonly called a “promo code”, so if you were looking for a Rainbet promo code, this is the code you need.
Why Rainbet Promo Code 2100BONUS May Not Work
If the Rainbet promo code 2100BONUS isn't being accepted, there are a few things you can check. While our codes are checked regularly and kept up to date, eligibility can still depend on your location, account, connection, or the way the code is entered.
Here are some of the most common reasons:
Restricted location - Rainbet promotions are not available in every country or territory. If you're located in a restricted area, the referral code will not be accepted.
VPN or proxy detected - Using a VPN, proxy, or other location-masking service can interfere with Rainbet's ability to verify your location. Try disabling it and accessing the site using your normal internet connection.
Internet or connection issues - A poor or unstable connection can prevent the referral code from being processed correctly. Refresh the page or try again once your connection is stable.
Code entered incorrectly - Make sure the code is entered exactly as shown. Avoid adding spaces before or after the code, and check for typing errors.
Temporary website issues - Occasionally, the referral system may experience a temporary technical problem. Waiting a little while and trying again can resolve the issue.
If the code did not enter during registration, there will be more opportunities to enter it, including within your account. If you are still having problems, contact the Rainbet customer service team.
Ongoing Rainbet Rewards & Rakeback
Rainbet is known to offer a great range of constant rewards that players can make the most of daily and weekly. The system can be quite confusing, so allow us to explain it to you.
What Is Rakeback at Rainbet?
As you may well already know if you've spent time at other rakeback casinos, rakeback is a reward that gives you a percentage of the bet value back. The amount of rakeback you can get is based on the following formula:
bet amount x house edge x 0.05
Rainbet VIP Club — Tiers & Rewards
Become a member of Rainbet’s VIP Club to access premium rewards, such as rakeback, daily, weekly, and monthly bonuses, plus personalised support for an exceptional gaming experience.
Rainbet Challenges provide you with the opportunity to win extra cash while playing particular slots or Original games.
To take part in any challenge, you just need to take a look at the list of options on the dedicated Challenges page. See if there is a game that takes your fancy, then load it up to start competing. Some challenges are harder to beat than others, although it is usually a case of bigger risk for bigger rewards.
You need to make sure your bet meets the minimum bet value requirements, otherwise your spins will not count towards the challenge.
Beat the multiplier target before anyone else and the associated cash prize will be yours. Some examples of what you could expect to find can be seen in the screenshot below.
